Wondering how this lens compares to the one mounted on the Sony Cyber-shot DSC-RX100. The two cameras have a near-identical size. Both are just pocketable, which renders them to be used at similar occasions.

- The Coolpix A's sensor is 3x the size = 1.5 stops of advantage over the RX100. (Both have Sony sensors of the same generation, so we can assume the same ability to capture light given per sensor surface area.)- The RX100 has an f1.8 lens = 1.3 stops advantage over the Coolpix A

That should equal slight advantage Nikon with regards to low-light performance. But the Sony has a zoom lens = more versatility.

In my limited experience with the Coolpix A, it's AF is quite (read VERY) slow compared to the RX100's. Forget about shooting action with the Coolpix A. (Please do correct me if I'm wrong on this. I only tried one at B&H.)

Wondering how much sharper the Nikon's images may be. The pictures coming out of my RX100 are not exactly super sharp even in the center.
